This looks interesting. I wonder if the star cluster in the paper can be seen visually? This looks like a good challenge object.

Hi Jimi,
The concerned star cluster is also NGC 5194 [HK83] 79.
The star above is Gaia 1551988665795368960, m15.022G, also Nomad 1371-0285015, m14.76V.
Both are easely seen in my 25" obsession, without looking precisely for them.
Here is a drawing from some years ago.

Does anyone know how to type the [HK83] entries in SIMBAD? I was unable to find the coordinates by trying "NGC 5194 [HK83] 79". In case anyone is interested, the coordinates from the paper (of the specific star, not the cluster, but "close enough" for our purposes):
13:29:43.30
+47:11:34.7
The knot itself looks doable in many amateur telescopes, I've to give it a shot next season.
Clear Skies!
You can find it in NED here, though perhaps you already knew that?
This HII knot is cataloged in SIMBAD as CCM 77. The designation is from thie 1969 French study "Kinematic study of ionized hydrogen in M51"
But as opposed to NED, SIMBAD doesn't have the Hodge-Kennicutt HII regions loaded into the database.
Long time ago, I wrote a .tdf file in Guide software from Project Pluto, that I use routinely , to display the HK83 HII regions.
Here are those of M51.
Hope that could help

I unfortunately forget that NED, the better database, exists :DQuote:
